FedEx Ground finally delivered my Mighty Mouse at about 8:15PM. It’s the most beautiful mouse I’ve ever seen, but I can’t say it’s the most comfortable. I’m used to a bigger mouse, but after a few minutes I didn’t find it uncomfortable. I didn’t install the software yet, but I found that USB OverDrive recognizes it and supports all the features including left & right scrolling. The scroll ball is extremely sensitive & quiet. I didn’t have any trouble right clicking, since I already tend to lift my finger off the left button when I right click. Middle Clicking is also pretty easy. I do have a bit of trouble with the side buttons, though. Squeezing feels a bit unnatural, but I can just ignore the right side button and click the left one with my thumb, like I click the left button on other mice. I’ll write a full review after I use it for a while and install the included software.
